Remote entanglement need not be the bottleneck for modular trapped-ion quantum computing
Felix W. Knollmann, David P. Nadlinger, John Blue +7
Modularity underpins classical computing; as quantum processors encounter limits on fabrication yield, reliability, and size, they will also need it acutely. The bottleneck to link…
Real-time magnetic field noise correction using trapped-ion monitor qubits
Kyle DeBry, Agustin Valdes-Martinez, David Reens +2
We demonstrate a trapped-ion protocol in which a nearby, dedicated "monitor" qubit tracks magnetic-field drifts in real time without interrupting data-qubit operations. Using two $…
Collection of fluorescence from an ion using trap-integrated photonics
Felix W. Knollmann, Sabrina M. Corsetti, Ethan R. Clements +12
Spontaneously emitted photons are entangled with the electronic and nuclear degrees of freedom of the emitting atom, so interference and measurement of these photons can entangle s…
Error correction of a logical qubit encoded in a single atomic ion
Kyle DeBry, Nadine Meister, Agustin Valdes Martinez +6
Quantum error correction (QEC) is essential for quantum computers to perform useful algorithms, but large-scale fault-tolerant computation remains out of reach due to demanding req…
